Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 4 to 7 illustrate a structure of a device for preventing thermal deformation of a fire door to which the present invention is applied.

The interior of the fire door main body 100 has a hollow space therein. The inner member and the outer member are spaced apart from each other so as to have an overall door shape. The circumference of the door member 110 is closed by the frame member 110, (150) is filled.

The heat insulating material 150 is filled with a resin material having a good thermal insulation effect and is fixedly attached to the inner space of the fire door main body 100 in a state in which the mutually connected state is maintained by a synthetic resin binder.

The door framing frame 200 is fixed to the building and surrounds the exterior of the fireproofing door body 100. A hinge 300 is connected to one side of the door frame frame 100 for opening and closing the door.

The door frame frame 200 is provided with a gas-impermeable gasket member 400 for forming a concave groove portion to insulate between the fire door main bodies 100 and to provide airtightness and sound insulation.

A gap of about 3-5 mm is formed between the frame frame 200 and the fire door main body 100 for smooth opening and closing. Thus, a gasket 600 having a "T" So that the wing portion can block a gap formed between the fire door main body 100 and the door frame 200 to facilitate opening and closing.
